How do I check the fuel economy on my car?

There are several ways to determine the actual fuel economy you’re getting from your Accord, but Honda actually states that the best option is “direct calculation”. That means you’re going to have to use math. Don’t worry, though. It’s really not that hard. Here’s what you need to do:

  1. Fill up the gas tank (stop when the nozzle clicks off).

  2. Clear your trip mileage (reset it to 0).

  3. Note the number of gallons pumped (not the cost).

  4. Drive until the tank is as close to empty as you can.

  5. Refill the tank.

  6. Use this formula to determine your fuel economy:

Miles driven divided by gallons of gas = MPG

Tip

You may need to do this with several tanks of gas to get an accurate idea of fuel economy.
